基于全生命周期的太阳能供暖系统经济性分析

Economic Analysis of Solar Heating System Based on Whole Life Cycle

结合太阳能供暖系统在实际建筑供暖现场的应用特点和全生命周期成本的概念,分析了太阳能供暖系统的构成、能耗特点以及成本构成,建立了一种太阳能供暖系统的全生命周期成本分析模型;基于全生命周期成本模型,分析了建筑面积、系统投资成本以及回收期之间的关系。最终通过文章研究得到如下结论:(1)各种成本中,初投资成本占全生命周期成本最高,其比值达到80%左右。(2)分析投资回收期得出:太阳能供暖系统虽然初期投资较高,但增加的投资可以在系统节约的运行费用中很快的收回,投资回收期一般在5年以内。

In view of the application characteristics of solar energy heating system in actual building heating site and the concept of whole life cycle cost,the composition,energy consumption and cost composition of solar energy heating system are analyzed.A whole life cycle cost analysis model of solar energy heating system is established.Based on the whole life cycle cost model,the relationship among building area,system investment cost and payback period is analyzed.Finally,through the research of this paper,we get the following conclusion:(1)among all kinds of costs,the initial investment cost is the highest in the whole life cycle cost,and its ratio is about 80%.(2)it is concluded that although the initial investment of solar heating system is high,the increased investment can be recovered quickly in the operation cost saved by the system,and the investment recovery period is generally within 5 years.
